STOVEPIPE-CLAMP.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed February 21, 1910. Serial No. 545,007.

To all whom it may concern:

Be it known that I, GEoRe R. BEEGEN, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inStovepipe-Clamps, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to means for preventing the sections of stovepipes from accidentally drawing apart at the joints when the sectionsare connected by the usual slipjoint.

To this end my invention consists in the peculiar construction,arrangement and operation of a clamp adapted to be applied to the stovepipe at the joints all as more fully hereinafter described and shown inthe. accompanying drawings, in which,

Figure 1 is an elevation of a section of stove pipe with my clampapplied to a joint thereof; Fig. 2 is a vertical axial section throughFig. 1; Fig. 3 is a detached perspective vlew of the clamp; and Fig. 4is an en larged partial section on line mw Fig. 1, embodying a slightmodification.

A A represents the adjacent male and female ends of two stove pipesections connected together in the usual manner by a slip joint.

My clamp consists of a sheet metal band B rolled into circular shape andof a length to nearly encircle the stove pipe at the joint.

This band is formed with marginal corrugations C large enough toaccommodate themselves to the corrugations usually ap plied to the stovepipe sections near the ends thereof, as for instance shown at D wheresuch corrugation serves as a stop for the slip joint. In forming thesecorrugations the free edges E thereof are made to pro} ject inwardly atan angle to a sufiicient degree to form clamping edges for the band aswill be shown more fully hereinafter. The open ends of this band areprovided with a locking device which consists of a lever F at one endand a hook G at the other end. The lever F is pivotally secured to earsa integrally formed from a plate H secured at the end of the band andthe hook Gr is formed of a looped piece of wire hinged to a strap I atthe other end of the band which strip is preferably pivot-ally securedthereto by a rivet b. The lever is provided with holes 0 formed atdifferent distances from its pivotal connection and adapted to engagewith the hook.

In practice the band being placed around the stove pipe at the joint andthe ends being locked together is intended to firmly clam the twosections of pipe together at the joint. In thus clamping the pipe, theinturned edges E of the band only bear against the pipe and since theseare inclined they are adapted to yield within a certain limit and bearagainst the pipe all around, so that in connection with theadjustability provided by the different holes 0, the clamp willaccommodate itself to Variations ordinarily existing in the size ofstove pipe sections of one kind.

It will be understood that the lever F is made self locking and inapplying the band the corrugation D is made to engage the correspondingcorrugation of the clamping band and thereby prevent endwisedisplacement. I consider it preferable that the band should notcompletely encircle the pipe but leave enough space for the seams of thepipe joints to pass between as shown in Fig. 1.

While I have described my device as applied to stove pipe only, Iinclude under such term all kinds of sheet metal pipe of like character,and I also do not confine myself to the specific construction of theclamping band as herein shown; an obvious modification consisting inmaking the band in halves hinged together, or in hinging the hook G toan eye I formed at the end of the band as shown in Fig. 4.

My device forms a safe guard for stove pipes to prevent the sagging anddisjointing of the sections especially for horizontal stretches of pipeand does away with the necessity of wiring it in position.

hat I claim as my invention is The combination with a stove pipe jointformed of telescoping sections, a sheet metal clamping band around thejoint provided with marginal corrugations terminating in inturned andoutwardly inclined clamping edges projecting beyond the inner face ofthe band and holding the same out of contact with the stove pipe, astrap pivotally for engagement with the free end of the secured upon oneend of the band and adapthook. 10 ed to have a limited angular movementon In testimony whereof I affiX my signature its pivot, a wire hookhaving a hinge joint in presence of two witnesses.
